Peel the cucumber and roughly cut two thirds of it into cubes, put in the blender. Add the sour cream, basil, lemon juice and a little salt and pepper. Puree, add seasoning if necessary.
Fry the prawns in a little oil and sprinkle with paprika.
Cut the remaining cucumber into small, bite-sized cubes.
Put the soup in a plate, cucumber pieces and prawns as well (or serve separately). Finally, drizzle the oil and paprika mixture over the soup.
Tip:
If you don`t like prawns, you can leave them out and just make the soup.
